Statement of Special Interest

A-Group with Breachacha Castle and Breachacha Steading (see separate listings).

Old Breachacha Castle is a fine 15th century tower house with associated walled outbuildings. It is unusual in having been built without vaults or mural fireplaces: the only other similar castle is Kisimul Castle, and it has been suggested that the two were designed by the same person, although the lack of dressings and other stylistic details makes both hard to date accurately. Having become ruinous in the 19th century, it was reconstructed and renovated for domestic use in the 1960s. This work was undertaken to the highest conservation standards of the time and was preceded by a thorough archaeological survey, the results of which are available at the RCAHMS and a written report in the Proceedings of the Society of Antiquaries for Scotland (see Refs). The majority of the 15th century fabric remained intact, door and window openings were left at their original size, the plan form was retained, and new elements added in a sympathetic and reversible manner.

In 1431 the island was granted to John Maclean, younger son of Lachlan Mclean of Duart, and it is believed that the first incarnation of the castle dates from this time, although the castle is not first mentioned until a charter in 1542, granting lands to the Macleans from James V. Hugh Maclean sold the Coll Estate to John Lorne Stewart in 1856 ending 4 centuries of Maclean ownership.

The first part of the castle to be built in the 15th century was the 4-storey tower house with integral stair, mural cupboards and garderobes within the wall thickness. Within this building phase the S and E sides of the castle were enclosed by a crenellated curtain wall, with a single storey hall to the courtyard and the prominent circular tower to the SE corner. In the late 16th century the original stair was replaced by a wider stair within the SE corner of the tower house wall. The castle underwent further stages of remodelling in the 16th and 17th centuries to include changes of openings and access. In the early 17th century a battery was added to the NW, enclosing the kitchen block in order to increase its defences to the landward side, although its construction was never finished. The last major development was in the late 17th century when the early hall was replaced by a 3-storey pitched-roof dwelling house visible from outside the wall.

The castle was superseded by the new castle in 1750 (see separate listing) but still remained in occupation for some time; the towerhouse roof is known to have been intact in 1843, after which point it fell into a derelict state. From 1930-38 general repairs were carried out to consolidate the ruin. In the 1930s Simpson described the castle as 'the most perfect and least altered example of a medieval stronghold in the Hebrides'.

The castle ruin was purchased in the 1960s and an archaeological survey was carried out by Turner and Dunbar. Breachacha Castle was then rebuilt to wallhead, re-roofed and converted into a family home to include modern conveniences in the later 1960s. The conversion was sensitive to the original plan layout with very few new openings or alterations to existing ones. This was possible due to a relaxation of building requirements secured by the architect Ian Lindsay (1906-1966) who was responsible for the initial project plans. The architect Richard Avery then took over the project which was finally completed in 1993. Most of the modern services are incorporated within garderobes and a former stair that had been closed off in the 16th century, minimising the need for modern partitions.

Kisimul Castle, Barra stands as good comparison also dating from the mid 15th century, and has a number of features in common with Breachacha having undergone similar stages of development before being abandoned in the mid 18th century and then restored in the mid 20th century.

The Ordnance survey map gives the spelling 'Breachacha', but the owner considers that 'Breacachadh' to be more correct.

About Listed Buildings

Historic Environment Scotland is responsible for designating sites and places at the national level. These designations are Scheduled monuments, Listed buildings, Inventory of gardens and designed landscapes and Inventory of historic battlefields.

We make recommendations to the Scottish Government about historic marine protected areas, and the Scottish Ministers decide whether to designate.

Listing is the process that identifies, designates and provides statutory protection for buildings of special architectural or historic interest as set out in the Planning (Listed Buildings and Conservation Areas) (Scotland) Act 1997.

We list buildings which are found to be of special architectural or historic interest using the selection guidance published in Designation Policy and Selection Guidance (2019)

Listed building records provide an indication of the special architectural or historic interest of the listed building which has been identified by its statutory address. The description and additional information provided are supplementary and have no legal weight.

These records are not definitive historical accounts or a complete description of the building(s). If part of a building is not described it does not mean it is not listed. The format of the listed building record has changed over time. Earlier records may be brief and some information will not have been recorded.

The legal part of the listing is the address/name of site which is known as the statutory address. Other than the name or address of a listed building, further details are provided for information purposes only. Historic Environment Scotland does not accept any liability for any loss or damage suffered as a consequence of inaccuracies in the information provided. Addresses and building names may have changed since the date of listing. Even if a number or name is missing from a listing address it will still be listed. Listing covers both the exterior and the interior and any object or structure fixed to the building. Listing also applies to buildings or structures not physically attached but which are part of the curtilage (or land) of the listed building as long as they were erected before 1 July 1948.

While Historic Environment Scotland is responsible for designating listed buildings, the planning authority is responsible for determining what is covered by the listing, including what is listed through curtilage. However, for listed buildings designated or for listings amended from 1 October 2015, legal exclusions to the listing may apply.

If part of a building is not listed, it will say that it is excluded in the statutory address and in the statement of special interest in the listed building record. The statement will use the word 'excluding' and quote the relevant section of the 1997 Act. Some earlier listed building records may use the word 'excluding', but if the Act is not quoted, the record has not been revised to reflect subsequent legislation.

Listed building consent is required for changes to a listed building which affect its character as a building of special architectural or historic interest. The relevant planning authority is the point of contact for applications for listed building consent.
